In this concise clinical monologue, Dr. Anne Truong explains that a penis, like any other muscle, can atrophy when it is not used. She describes her observations of men who have experienced prolonged periods without sexual activity, noting that their penile tissue becomes fibrous and hard, the shaft can retract beneath the foreskin, and urinary flow may become difficult. The discussion links these physical changes to erectile dysfunction and underscores the importance of regular sexual activity to maintain penile health.

Think of your penis like your biceps. You don't use it, you're going to lose it. And it actually does atrophy. I have seen it in my clinic. I see men who has ED, have not had sex for years. Their penis feels very fibrous. Fibrous means hard. It feels like when you touch something, it's like scarred down. The muscles are not as squishy or spongy. It really feels hard. The penis looks like a boy's penis. It literally shrunk. And sometimes the shaft will kind of go inside to the foreskin because it shrinks. So the foreskin is covering all the shaft and the guy sometimes even has a hard time going urinate.
